Well I tell ya...I got a set of airhorns on my Jeep too. Tryed all kinds of them...semi horns, boat horns, italian ones....but before I had onboard air, I had these cheesy lil plastic ones that had like a 3oz air compressor that came with them.
Well I liked the Italian ones, but they too had a compressor that had come with them and I was afraid that I would blow them up with the onboard air. So I figured that I would try the plastic tripple horns that I had....if I blew those up...no biggie.
Well let me tell ya...WHeee doggies....you take them cheepie horns and CRANK 130lbs of air through them....and they just SCREAM!
A sure cure for the ol "road rage". I don't get mad....I just give them the "horn"!!
PS and them animals in the roadway shift into high gear when I go by.
